It is, on average, the warmest month in most of the Northern hemisphere (where it is the second month of summer) and the coldest month in much of the Southern hemisphere (where it is the second month of winter).
The second half of the year commences in July. In the Southern
hemisphere, July is the seasonal equivalent of January in the Northern
hemisphere.

July starts on the same day of the week as April in a common year,
and January in leap years. In a common year no other month ends on the
same day as July, while in a leap year July ends on the same day of the
week as January.
